Abstract

An endoscope apparatus includes light source means, imaging means, density calculating means, and image processing means, wherein the image processing means changes frequency processing conditions with respect to the captured image such that the detection and enhancement degree of the structure and components of the living body in the subject are changed according to at least the density of each pixel of the captured image.
